三维计算模型的网格划分及可视化平台的开发

摘要

Taking the computation of current and magnetic field distribution of model's conductive surface, as example, the principle of meshing, method of coefficient determination, and methods of uniform and non-uniform meshing were explored for 3-D computational model and a complete platform for meshing and visualization of 3-D computational models was developed. A car and an air-plane produced actually in industry were tested as a model during experiment The result showed that for models with complex geometry, the developed platform could be used to perform appropriate meshing and give flickerless display. The implementation of this platform would provide a good basis for developing more complete 3-D modeling software.%以计算导体模型表面电流及磁场分布为例,对三维计算模型的网格划分原理、系数的确定方法以及均匀和非均匀网格的划分方法进行探讨,开发了完整的三维模型的网格划分及可视化平台.实验采用工业生产中真实的汽车和飞机模型,结果表明该平台能够对复杂几何模型进行网格划分及三维无闪烁显示.该平台的实现对于开发更为完备的三维建模软件提供良好的基础.
